According to Arkham intelligence, the German government no longer has any BTC in its reserves, they dumped ~ 50,000 BTC's, and i believe that is all the BTC's they have 'acquired' from assets they have seized in the past.
but it could have been better if the German government held on to it until they reached 6 digits but its already profit for them at whatever price they want to sell.
That is not what the German government cares about, they are not BTC investors and the coins they have is from assets seizures, it is not so much about storing it for profits. They were selling most of these coins in the OTC market, and it was a bad period for the price of BTC, i think now it will recover, except for Mt. Gox's reimbursements that is coming soon, that could also keep the price down.
